def function():

    while True:  

        ...omission...(this function is repeated permanently)

i =0

while i < 4:

    driver.execute_script("""window.open("URL")""")

    driver.switch_to.window(driver.window_handles[-1])

    time.sleep(1)

    function()

    time.sleep(1)

    i += 1  #open new tab and run function.

它不起作用，因为 while true 循环永久重复。有没有办法同时运行多个功能？ https://imgur.com/a/4SIVekS这张图显示了我想要的
